Intra- and Inter-Rater Agreement Describing Myometrial Lesions Using Morphologic Uterus Sonographic Assessment : A Pilot Study

摘要: OBJECTIVES: To evaluate the intra- and inter-rater agreement for myometrial lesions using Morphologic Uterus Sonographic Assessment terminology. METHODS: Thirteen raters with high (n = 6) or medium experience 7) assessed 30 3-dimensional ultrasound clips 20) without 10) benign lesions. Myometrial were reported as poorly well defined then systematically evaluated presence of individual features. The blindly twice (at a 2-month interval). Intra- agreements calculated κ statistics. RESULTS: reporting reached moderate intra-rater (κ 0.49 [high experience] 0.47 [medium experience]) poor 0.39 0.25 experience]). well-defined good to very 0.73 0.82 0.75 0.63 Most features associated ill-defined among highly experienced 0.41-0.60). least reproducible cysts, hyperechoic islands, subendometrial lines buds, translesional flow 0.11-0.34). all observers 0.41-0.80). serosal contour, asymmetry, rim, fan-shaped shadows 0.00-0.35). CONCLUSIONS: showed excellent agreement, whereas was low, even raters. on identifying varied, especially Guidelines minimum requirements be interpreted may improve agreement. (Less)
